In any Mine, there are many risk factors. In order to safe guard the people working inside the mine its
environmental parameters are monitored. The hardware consisted of electronic circuitry where a microcontroller is the
principal processing unit. A graphical user interface is also implemented. A number of qualification tests are carried
out. The temperature, humidity, airflow and noise sensor measurements have an accuracy of 89.01%, 98.55%, 90.5%,
89.53% and a resolution of 0.105°C, 0.12% RH, 0.05m/s and 0.23 dB SPL respectively. In addition gas and dust sensors
met the specification; however, the accuracy could be improved. Since the consequences of mining cannot be avoided, its
effect can be predicated in order for safety precautions.. The monitored parameters can be send using IOT modem and
IBEACON Devices.
